Benefits of technology
The present invention relates to a display panel driving apparatus that includes a gate driving circuit, a data driving circuit, a timing controlling circuit, and a voltage generating circuit state receiving circuit. The voltage generating circuit state receiving circuit receives voltage generating circuit data indicating the temperature, voltage, or current of the voltage generating circuit that generates voltage to drive the display panel. The circuit then outputs a control signal to the timing controlling circuit to control its operation. The timing controlling circuit controls the output of the data signal and the gate signal to the display panel. The technical effect of this invention is to provide a more efficient and accurate display panel driving apparatus that compensates for changes in voltage generating circuit conditions, such as temperature, to ensure optimal performance.
Problems solved by technology
However, when the voltage generating part operates abnormally during the driving of the display panel the display quality of an image displayed on the display panel may be degraded.
In addition, the gate driving part, the data driving part and the timing controlling part in the display apparatus may be damaged.
